Claims of anxiolysis come from limited clinical literature; quality varies.

Anxiety symptom measures
Low
Population: Patients with generalized anxiety disorder/neurasthenia (reported clinical study)
Study type: Clinical-biological study (older literature)
Dose context:

Clinical literature reports anxiolytic effects in patient cohorts, but study designs and reporting standards vary and limit certainty.

Anxiolytic effect vs. phenazepam in anxiety disorders
Low
Population: 60 patients with phobic-anxiety and somatoform disorders
Study type: Comparative clinical study
Dose context:

Selank showed pronounced anxiolytic and mild nootropic effects compared with phenazepam; the anxiolytic effect persisted for approximately one week after the last dose. Methodology reflects older Russian clinical reporting standards, limiting generalizability.
